My wife and I will be spending the first 3 weeks of April 2017 in Australia. We’ll be in Sydney the first week, and then 4 days at Ayers Rock. We have no plans for the remaining 10 days – and we didn’t realize we’d be there during Easter. We’d like to go to the southern GBR, perhaps flying in to Brisbane and going on to somewhere exotic from there. Snorkeling is a must at some point in the trip. Any suggestions for any leg of our journey would be greatly appreciated. I don’t want to mine Trip Advisor for hints and be around nothing but Americans, and prefer to avoid the Tourist Traps. Thanks in advance for any & all advice.
